IBM 000-274 Exam : IBM WebSphere DataPower SOA Appliances Firmware V5.0 Solution Implementation

A web service proxy is receiving orders from partners as SOAP messages. The service is required to reject messages if the total order cost in themessage does not match the sum of the individual item costs. What can the solution implementer do to support this requirement?

• A. Create a style sheet which performs the mathematical comparison and uses either a <dp:accept> or <dp:reject>, and use this in a Filter action.
• B. Define the requirement in a WS-Policy attachment for the service. The web service proxy will then automatically perform the mathematical comparison and reject any invalid messages.
• C. Create an XML Schema that enforces the above business requirements and uses this schema in a Validate action.
• D. Configure an SLM Statement with the Threshold Level that computes the total order cost, and if it does not match the totalvalue then throttle the transaction.

A solution implementer needs to integrate a DataPower appliance with an IMS COBOL application. The multi-protocol gateway is created with an HTTP Front Side Handler and an IMS Connect backside URL of the form dpims://. The EBCDIC HeaderConversion is configured as "on" in the IMS Connect object. What benefit(s) can the solution implementer achieve by using this Header Conversion option?

• A. Converts IMS headers to ASCII encoding
• B. Converts bothIMS headers and payload to ASCII encoding
• C. Converts both IMS headers and payload to EBCDIC encoding
• D. Converts IMS headers to EBCDIC encoding

Which networkprotocol does the "Ping Remote" DataPower function use to test network connectivity to a remote system?

• A. ICMP
• B. Multicast UDP
• C. ARP
• D. HTTP

A solution implementer needs to configure the appliance to throttle transactions if the device memory utilization reaches 70%. What can the solution implementer do to achieve the desired result?

• A. Memory management is an internal DataPower function and cannot be configured.
• B. Configure an SLM action to throttle transactions when memory reaches 70%.
• C. Configure Throttle Settings and set the Memory Throttle threshold to 30%.
• D. Configure the Statistic Settings with load interval of 1 and memory threshold to 30%.

The solution implementer configured a multi-protocol gateway (MPGW) service to process WebSphere MQ messages using the same MQ queue manager object for both the front
end and back end. A request rule in the processing policy sends a message to queue A and then to queue B in a single transaction by using a "Result Action". The MQ URL forthe back end contains the "Transactional=true" tag. The output type of the "Result Actions" is set as "Binary" and the OUTPUT context has a named variable. What are the additional configuration options that the solution implementer needs to guarantee message delivery for both back-end queues? Specifically, if any one message fails, the entire transaction will roll back.

• A. DataPower cannot support this use case as an MQ queue manager object only works with global transactionality.
• B. Configure "Units of Work = 1" and "Automatic Backout = off "in the MQ queue manager object.
• C. Configure "Units of Work = 1" and "Automatic Backout = on"; "Backout Threshold" and "Backout Queue" defined in the MQ queue manager object.
• D. Configure two phase commit in the backend WebSphere MQ queue manager.
